Aldehyde dehydrogenases are a group of enzymes that catalyse the oxidation (dehydrogenation) of aldehydes. Multiple forms exist in mammals in the cytosol, mitochondria and endoplasmic reticulum. They have been classified as Class 1 (cytosolic), Class 2 (mitochondrial) and Class 3 (tumour and other isozymes).

[Aldehyde dehydrogenases are] isoenzymes important in cell defence against both exogenous and endogenous aldehydes.

Les aldéhydes déshydrogénases sont des flavoprotéines hépatiques qui captent les aldéhydes et les oxydent en acides. Il existe plusieurs isoenzymes catalysant ces réactions, dans le cytoplasme ou les mitochondries de nombreuses cellules : foie, rein, cerveau, globules rouges. Au cours de l'oxydation de l'acétaldéhyde, un coenzyme NAD+ est encore réduit, et l'acide acétique produit est lié au coenzyme A par une liaison riche en énergie. L'acétyl-CoA issu de ce métabolisme pénètre dans la mitochondrie devient un substrat du cycle de Krebs.

A tanning method using a formalin solution in the manufacture of white leathers and also washable glove leathers.

OBS

Formaldehyde is dissolved in water to create formalin and used as the tanning solution primarily to produce leather which is white in color and washable; commonly used for tanning deerskins with the grain removed [but] yellowing occurs upon aging [and] grain leathers tanned with formaldehyde can be subject to "cracky" grain.

Rigid materials are exemplified by the decorative high-pressure laminates whose integral melamine-formaldehyde surface is harder than conventional varnishes or lacquers.

Gluing. Urea-Formaldehyde (UF) Resin. Melamine-Formaldehyde (MF) Resin. Phenol-Formaldehyde (PF) Resin. Isocyanate (MDI) Polymer. MF resin is used sparingly for engineered wood products and only in combination to improve the strength of UF-bonded MDF and PB.

CONT

Melamine formaldehyde (MF) thermoset products became leading members of the amino resin family, including urea and thiourea, because of superior properties. MF resins were developed through the 1930s and 1940s in companies such as American Cyanamid, Ciba and Henkel. Early applications, including fabric impregnation and adhesives, were followed by the introduction of moulding powders containing cellulosic fibres, pigments and fillers.

Short-chain aldehydes are produced from fatty hydroperoxides but are also found in vegetals. Long-chain aldehydes occur in free form but are frequently included in complex lipids in the form of vinyl ether (plasmalogen analogs of glycerides or phospholipids).

CONT

The bioluminescent reaction of luciferase isolated from "Vibrio harveyi," strain M17, was initiated by mixing the intermediate luciferase-bound flavin-4alpha-hydroperoxide, purified in advance, with a long chain aldehyde (dodecanal or octanal) at -4°C.
